How to make my pawn go to the ground

I made a character and a pawn. So now the character can switch from the character itself to a pawn(jetplane)
Now I finished to make the jetplane launch upward so they can fly straightaway.
I did that by using the jump key followed by a flip flop. The A is the one that make it launch upward (working perfectly fine)
Now I cant seems to find a way for the B to make it go back down to the ground (parking-like) If u need to look at my BP, I will show it later on if u ask. For now, can you atleast give me some help regarding this?
Thank you.

ps/ I am still learning so I am sorry if this is a simple task.

My second thread this week on different question but still no answer. Is there anyone can help here ? Or any other forums I can ask help
